Slice bread loves horizontally to assemble an easy rectangular layered sandwich cake. Cut off the bread crusts and use them to make homemade bread crumbs (we're a no waste kitchen).
Place the first slice of whole wheat bread on a rectangular serving platter. Spread some of the Smörgåstårta Frosting all over the bread slice.
Top icing layer with egg salad mixture and spread evenly.
Add a layer of rye bread and gently press onto egg salad. Top with more Smörgåstårta icing and top with German ham salad.
Continue alternating whole wheat bread slices and rye bread slices with the two creamy cold salads.
Once you've added the last bread slice to the top of the sandwich cake, smear with creamy frosting.
Surround the rim of the cake with quartered cherry tomatoes. Decorate the interior space with thinly sliced lemons, cucumber and radish.
Use a palette knife to smear the remaining icing on the sides of the cake. Lightly pat finely chopped chives to the sides of the cake. The fresh herbs should stick to the icing.
Store Smörgåstårta in the fridge until ready to serve. Plate as you would a traditional dessert cake.
